Re: [Discuss-gnuradio] Looking for books and online courses on gnuradio?
Tom, Thanks a lot for your email. I appreciate your feedback. I guess that your and Dr. Wyglinski's book will be helpful for me. I will try to get these books through my library and see how it goes from there.

Re: [Discuss-gnuradio] minor bug
Tom, I tried some more to clean up the dependencies list on Ubuntu. I found a few dependencies that we were installing that don't seem to be needed. ./configure, make and make check pass without errors. Can you please confirm that in fact they are not necessary? Thanks! * guile and guile-1.8-dev * python-opengl * pyqt4-dev-tools and qt4-dev-tools * libqwtplot3d-qt4-dev What's more, there are a few dependencies that don't need to be stated explicitly, as they get pulled in automatically by other packages we install: * libpulse-dev (pulled in by libsdl1.2-dev) * sdcc-libraries (pulled in by sdcc) * libqt4-dev (pulled in by libqwt5-qt4-dev) * libqtcore4 (pulled in by python-qwt5-qt4) Finally, there are three dependencies of gr-qtgui that are not checked by ./configure (i.e. configure passes, but make fails): * libfontconfig1-dev * libxrender-dev * libxi-dev Dimitrios Symeonidis "If you think you're too small to make a difference, try sleeping with a mosquito!" - Amnesty International On 28 August 2011 18:08, Dimitris Symeonidis wrote: > On 27 August 2011 23:10, Tom Rondeau wrote: >> On Fri, Aug 26, 2011 at 10:00 AM, Dimitris Symeonidis >> wrote: >>> I noticed that the "docs" component passes the configuration tests >>> even without doxygen installed.

Re: [Discuss-gnuradio] Two instances of QT GUI Sink in a single program
Thanks Tom. I guess I did not make myself clear. I do have several QT GUI blocks in the program, which I indeed generate using GRC. I have many sliders, a checkbox, and a sink (FFT). If I add a slider, I see it on the screen when I run the new program. When when I add a sink block, there is still only one FFT display, showing the results from one of the FFT blocks. The problem is only with the QT Sink block, not with all the QT blocks. Sivan The attached .grc file has TWO QT-GUI sinks, and they are both displayed. Now, I have to grow the window in order to see them both, since they each take up a fair amount of real-estate. -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org qtguifft.grc Description: application/gnuradio-grc ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

This used to be required in order for ./configure to check for the existence of the python headers (python-dev), or else ./configure would claim that Python.h is missing.
